4.4 Performance characteristics

Drive performance is characterized by the following parameters:

Command Overhead Mechanical Positioning

Seek Time Latency

Data Transfer Speed

Buffering Operation (Look ahead/Write Cache)

Note: All the above parameters contribute to drive performance. There are other parameters which contribute to the performance of the actual system. This specification defines the essential characteristics of the drive. This specification does not include the system throughput as this is dependent upon the system and the application.

The following table gives a typical value for each parameter. Function

Table 5 Mechanical positioning performance

Typical and Max. are defined throughout the performance specification as follows:

Typical Average of the drive population tested at nominal environmental and voltage conditions. Max. Maximum value measured on any one drive over the full range of the environmental and

voltage conditions. (See section 6.1, "Environment" and section 6.2, "DC power requirements" )

The seek time is measured from the start of motion of the actuator to the start of a reliable read or write operation. A reliable read or write operation implies that error correction/recovery is not employed to correct arrival problems. The Average Seek Time is measured as the weighted average of all possible seek combinations. max.  (max. + 1 – n)(Tnin + Tnout) n=1 Weighted Average = –––––––––––––––––––––––––––– (max. + 1)(max)

Where: max. = maximum seek length n = seek length (1-to-max.)

Tnin = inward measured seek time for an n-track seek

Tnout = outward measured seek time for an n-track seek

4.4.1.2 Full stroke seek

Command Type Typical (ms) Max. (ms)

Read/Write 25.0 30.0

Table 6 Full stroke seek time

Full stroke seek time in milliseconds is the average time of 1000 full stroke seeks.

4.4.2 Operating modes

Operating mode Description

Spin-Up Start up time period from spindle stop or power down. Seek Seek operation mode

Write Write operation mode Read Read operation mode Performance idle

The device is capable of responding immediately to media access requests. All electronic components remain powered and the full frequency servo remains operational.

Active idle

The device is capable of responding immediately to media access requests. Some circuitry—including servo system and R/W electronics—is in power saving mode. The head is parked near the mid-diameter the disk without servoing.

A device in Active idle mode may take longer to complete the execution of a command because it must activate that circuitry.

Low power idle The head is unloaded onto the ramp position. The spindle motor is rotating at full speed.

Standby

The device interface is capable of accepting commands. The spindle motor is stopped. All circuitry but the host interface is in power saving mode.

The execution of commands is delayed until the spindle becomes ready. Sleep The device requires a soft reset or a hard reset to be activated. All electronics,

including spindle motor and host interface, are shut off.

4.4.2.2 Operating mode at power on

The device goes into Idle mode after power on or hard reset as an initial state..

4.4.2.3 Adaptive power save control

The transient timing from Performance Idle mode to Active Idle mode and Active Idle mode to Low Power Idle mode is controlled adaptively according to the access pattern of the host system. The transient timing from Low Power Idle mode to Standby mode is also controlled adaptively, if it is allowed by Set Features Enable Advanced Power Management subcommand.

(22)

5 Data integrity

5.1 Data loss on power off

Data loss will not be caused by a power off during any operation except the write operation. A power off during a write operation causes the loss of any received or resident data that has not

been written onto the disk media.

A power off during a write operation might make a maximum of one sector of data unreadable. This state can be recovered by a rewrite operation.

5.2 Write Cache

When the write cache is enabled, the write command may complete before the actual disk write operation finishes. This means that a power off, even after the write command completion, could cause the loss of data that the drive has received but not yet written onto the disk.

In order to prevent this data loss, confirm the completion of the actual write operation prior to the power off by issuing a

Soft reset Hard reset

Flush Cache command Standby command

Standby Immediate command Sleep command

Confirm the command’s completion.

5.3 Equipment status

The equipment status is available to the host system any time the drive is not ready to read, write, or seek. This status normally exists at the power-on time and will be maintained until the following conditions are satisfied:

The access recalibration/tuning is complete.

The spindle speed meets the requirements for reliable operation. The self-check of the drive is complete.

The appropriate error status is made available to the host system if any of the following conditions occur after the drive has become ready:

The spindle speed lies outside the requirements for reliable operation. The occurrence of a Write Fault condition.

5.4 WRITE safety

The drive ensures that the data is written into the disk media properly. The following conditions are monitored during a write operation. When one of these conditions exceeds the criteria, the write operation is terminated and the automatic retry sequence is invoked.

Head off track External shock Low supply voltage

Spindle speed out of tolerance Head open/short

(23)

5.5 Data buffer test

The data buffer is tested at power on reset and when a drive self-test is requested by the host. The test consists of a write/read '00'x and 'ff'x pattern on all buffers.

5.6 Error recovery

Errors occurring on the drive are handled by the error recovery procedure.

Errors that are uncorrectable after application of the error recovery procedure are reported to the host system as non-recoverable errors.

5.7 Automatic reallocation

The sectors that show some errors may be reallocated automatically when specific conditions are met. The drive does not report any auto reallocation to the host system. The conditions for auto reallocation are described below.

5.7.1 Non-recovered write errors

When a write operation cannot be completed after the Error Recovery Procedure (ERP) is fully carried out, the sectors are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation has failed.

5.7.2 Non-recoverable read error

When a read operation fails after ERP is fully carried out, a hard error is reported to the host system. This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verification is performed automatically. When the result of this verification meets the required criteria, this sector is reallocated.

5.7.3 Recovered read errors

When a read operation for a sector fails and is recovered at the specific ERP step, the sector is

reallocated automatically. A media verification sequence may be run prior to the reallocation according to the predefined conditions.

5.8 ECC

The 10 bit 40 symbol non interleaved ECC processor provides user data verification and correction capability. The first 6 symbol of ECC are 4 check symbols for user data and the 2 symbol system ECC. The other 34 symbols are Read Solomon ECC. Hardware logic corrects up to 16 symbols(20 bytes) errors on-the-fly.

2 symbol System ECC is generated when HDC receives user data from HOST, and can correct up to 1 symbol(10bit) errors on-the-fly when one transfers to HOST.

6.3 Reliability

6.3.1 Data reliability

 Probability of not recovering data is 1 in 1014bits read  ECC implementation

On-the-fly correction performed as a part of read channel function recovers up to 16 symbols of error in 1 sector (1 symbol is 10 bits).

6.3.2 Failure prediction (S.M.A.R.T.)

The drive supports Self-monitoring, analysis and reporting technology (S.M.A.R.T.) function. The details are described in section 12.8, "S.M.A.R.T. Function" and in Section 14.40, "S.M.A.R.T. Function Set (B0h)"

6.3.3 Cable noise interference

To avoid any degradation of performance throughput or error when the interface cable is routed on top or comes in contact with the HDA assembly, the drive must be grounded electrically to the system frame by four screws. The common mode noise or voltage level difference between the system frame and power cable ground or AT interface cable ground should be in the allowable level specified in the power requirement section.

6.3.4 Service life and usage condition

The drive is designed to be used under the following conditions:

The drive should be operated within specifications of shock, vibration, temperature, humidity, altitude, and magnetic field.

The drive should be protected from ESD.

The breathing hole in the top cover of the drive should not be covered. Force should not be applied to the cover of the drive.

The specified power requirements of the drive should be satisfied.

The drive frame should be grounded electrically to the system through four screws. The drive should be mounted with the recommended screw depth and torque.

The interface physical and electrical requirements of the drive should satisfy Serial ATA Revision 2.6.  The power-off sequence of the drive should comply with the 6.3.6.2,"Required power-off sequence.” Service life of the drive is approximately 5 years or 20,000 power on hours, whichever comes first, under the following assumptions:

 Less than 333 power on hours per month.

 Seeking/Writing/Reading operation is less than 20% of power on hours.

This does not represent any warranty or warranty period. Applicable warranty and warranty period are covered by the purchase agreement.

(28)

6.3.6 Load/unload

The product supports a minimum of 600,000 normal load/unloads.

Load/unload is a functional mechanism of the hard disk drive. It is controlled by the drive micro code. Specifically, unloading of the heads is invoked by the following commands:

Standby

Standby immediate Sleep

Load/unload is also invoked as one of the idle modes of the drive.

The specified start/stop life of the product assumes that load/unload is operated normally, not in emergency mode.

6.3.6.1 Emergency unload

When hard disk drive power is interrupted while the heads are still loaded the micro code cannot operate and the normal 5-volt power is unavailable to unload the heads. In this case, normal unload is not possible. The heads are unloaded by routing the back EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case and the unload process is inherently less controllable without a normal seek current profile.

Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload.

The drive supports a minimum of 20,000 emergency unloads.

6.3.6.2 Required Power-Off Sequence

The required host system sequence for removing power from the drive is as follows: Step 1: Issue one of the following commands.

Standby

Standby immediate Sleep

Note: Do not use the Flush Cache command for the power off sequence because this command does not invoke Unload.

Step 2: Wait until the Command Complete status is returned.

The host system time out value needs to be 30 seconds considering error recovery time. Step 3: Terminate power to HDD.

This power-down sequence should be followed for entry into any system power-down state, system suspend state, or system hibernation state. In a robustly designed system, emergency unload is limited to rare scenarios, such as battery removal during operation.

6.3.6.3 Power switch design considerations

In systems that use the Travelstar Z5K320 consideration should be given to the design of the system power switch.

Hitachi recommends that the switch operate under control of the host system, as opposed to being hardwired. The same recommendation is made for cover-close switches. When a hardwired switch is turned off, emergency unload occurs, as well as the problems cited in section 5.1, "Data loss by power off" and section 5.2, “Write Cache”.

6.3.6.4 Test considerations

Start/stop testing is classically performed to verify head/disk durability. The heads do not land on the disk, so this type of test should be viewed as a test of the load/unload function.

(29)

Start/Stop testing should be done by commands through the interface, not by power cycling the drive. Simple power cycling of the drive invokes the emergency unload mechanism and subjects the HDD to non-typical mechanical stress.

Power cycling testing may be required to test the boot-up function of the system. In this case Hitachi recommends that the power-off portion of the cycle contain the sequence specified in section 6.3.6.2, "Required Power-Off Sequence”. If this is not done, the emergency unload function is invoked and non-typical stress results.

Connector specifications are included in section 7.2, "Interface connector".

6.4.4 Mounting orientation

The drive will operate in all axes (six directions) and will stay within the specified error rates when tilted ±5 degrees from these positions.

Performance and error rate will stay within specification limits if the drive is operated in the other

permissible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa.

The recommended mounting screw torque is 0.3±0.05 Nm.

The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting.

The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation.

6.4.5 Load/unload mechanism

The head load/unload mechanism is provided to protect the disk data during shipping, movement, or storage. Upon power down, a head unload mechanism secures the heads at the unload position. See section 6.5.4, "Non-operating shock" for additional details.

11 Registers

In Serial ATA, the host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. Shadow Register Block registers are interface registers used for delivering commands to the device or posting status from the device. About details, please refer to the Serial ATA Specification.

In the following cases, the host adapter sets the BSY bit in its shadow Status Register and transmits a FIS to the device containing the new contents.

 Command register is written in the Shadow Register Block

 Device Control register is written in the Shadow Register Block with a change of state of the SRST bit

 COMRESET is requested

11.1 Register naming convention

This specification uses the same naming conventions for the Command Block Registers as the ATA8-ACS standard. However, the register naming convention is different from that uses in the Serial ATA 2.6 specification. The following table defines the corresponding of the register names used in this specification with those used in the Serial ATA 2.6 specification.

Table 28 Status Register

This register contains the device status. The contents of this register are updated whenever an error occurs and at the completion of each command.

If the host reads this register when an interrupt is pending, it is considered to be the interrupt acknowledge. Any pending interrupt is cleared whenever this register is read.

If BSY=1, no other bits in the register are valid. Bit Definitions

BSY Busy. BSY=1 whenever the device is accessing the registers. The host should not read or write any registers when BSY=1. If the host reads any register when BSY=1, the contents of the Status Register will be returned.

DRDY (RDY) Device Ready. RDY=1 indicates that the device is capable of responding to a command. RDY will be set to 0 during power on until the device is ready to accept a command.

DF Device Fault. DF=1 indicates that the device has detected a write fault condition. DF is set to 0 after the Status Register is read by the host.

DSC Device Seek Complete. DSC=1 indicates that a seek has completed and the device head is settled over a track. DSC is set to 0 by the device just before a seek begins. When an error occurs, this bit is not changed until the Status Register is read by the host, at which time the bit again indicates the current seek complete status.

When the device enters into or is in Standby mode or Sleep mode, this bit is set by device in spite of not spinning up.

DRQ Data Request. DRQ=1 indicates that the device is ready to transfer a word or byte of data between the host and the device. The host should not write the Command register when DRQ=1.

CORR (COR) Corrected Data. Always 0.

IDX Index. Always 0

ERR ERR=1 indicates that an error occurred during execution of the previous command. The Error Register should be read to determine the error type. The device sets ERR=0 when the next command is received from the host.

12 General Operation Descriptions

12.1 Reset Response

There are three types of reset in ATA as follows:

Power On Reset (POR) The device executes a series of electrical circuitry diagnostics, spins up the HDA, tests speed and other mechanical parametric, and sets default values.

COMRESET COMRESET is issued in Serial ATA bus.

The device resets the interface circuitry as well as Soft Reset.

12.1.1 Register Initialization

After power on, COMRESET, or software reset, the register values are initialized as shown in the following table.

Register Default Value

Error Diagnostic Code

Sector Count 01h LBA Low 01h LBA Mid 00h LBA High 00h Device 00h Status 50h Alternate Status 50h

Table 30 Default Register Values

The meaning of the Error Register diagnostic codes resulting from power on, COMRESET or the Execute Device Diagnostic command are shown in the following table.

Code Description 01h No error Detected

02h Formatter device error 03h Sector buffer error 04h Ecc circuitry error

05h Controller microprocessor error Table 31 Diagnostic Codes

12.2 Diagnostic and Reset considerations

The Set Max password, the Set Max security mode and the Set Max unlock counter don’t retain over a Power On Reset but persist over a COMRESET or Soft Reset.

For each Reset and Execute Device Diagnostic, the Diagnostic is done as follows: Execute Device Diagnostic

In all the above cases: Power on, COMRESET, Soft reset, and the EXECUTE DEVICE DIAGNOSTIC command the Error register is shown in the following table.

Device 0 Passed Error Register

Yes 01h

No 0xh

Where x indicates the appropriate Diagnostic Code for the Power on, COMRESET, Soft reset, or Device Diagnostic error.
